Update更新
Just wanted to add an update on this question - finally, i was able to get FileUpload working but I had to start fresh, i created FileUploadController again and did all wiring again and now it seems to be working fine.只是想在这个问题上添加一个更新 - 最后，我能够让 FileUpload 工作，但我必须重新开始，我再次创建 FileUploadController 并再次进行所有接线，现在它似乎工作正常。 Still, I am not able to figure out what was the issue of earlier errors.尽管如此，我还是无法弄清楚早期错误的问题是什么。

I don't see the tag (mvc:annotation-driven) in your spring context file.我在您的 spring 上下文文件中看不到标签（mvc：annotation-driven）。 Please add that to your context file that should resolve the problem.请将其添加到应该解决问题的上下文文件中。

If CLASSPATH means environment variable to you, then that's your problem.如果 CLASSPATH 对您来说意味着环境变量，那么这就是您的问题。
You need to have all your dependency JARs in your app's WEB-INF/lib directory OR in the /lib directory for your app server.您需要将所有依赖项 JARs 放在应用程序的 WEB-INF/lib 目录或应用程序服务器的 /lib 目录中。 (Preferrably the WEB-INF/lib.) （最好是 WEB-INF/lib。）
Delete your CLASSPATH environment variable;删除您的 CLASSPATH 环境变量； it's not necessary, and it's done nothing but misled you in this case.这不是必需的，在这种情况下它只会误导你。
